Summary: Our look back at the history of Stargate Atlantis continues this week with an episode-by-episode walk through Season Two! This year introduced some important characters and storylines (Michael and the hybrids, Colonel Caldwell, the iratus bug retrovirus), strong episodes that delivered both adventure and thoughtful character stories, but also a few stories that didn't do it for us. We'll talk about everything from "The Siege, Part 3″ to "Allies," the departure of Aiden Ford, the addition of Ronon Dex to the team, and more. (Look for the Episode #78 Show Notes now at GateWorld.net.)
